So my brother in law has a whole second life. Him and my SIL have 2 kids and shes pregnant with #3. He comes to me to talk to because he lives in the house with her parents, I'm also the only other spouse who is not blood related to the family and he doesnt have family in CA.

Idk why but I feel guilty having knowledge of his second life. He has another name. Supposedly hes not a social media person well from what he acts like to her but he has instagram snapchat and facebook all in his other name he also doesn't claim his family or even his kids. He travels out of town alot for work and I could only imagine the things he does but again I just dont know what to do. Telling you all on here kinda feels better but idk.
